Extremely helpful. I use it as a reminder to stop using social media and do something productive instead while helping my eyes. Pressing start twice is a real pain though, it would be extremely nice if they made it one click to start the countdown.

Awesome extension. Wonder why it's not more popular

It was very best when i first use, single click started the countdown, now the updated version need to click twice.... Also User Interface was better (For me) then this new one.

Not even appearing on toolbar above.Rest extensions are appearing, i don't know what's the problem with this extension.

Worked when it wanted to.

Would not work with YouTube full screen after the first notification. I was watching a video on YouTube for more than 40 minutes, and the notifications would not appear after the first one.

Casual browsing of the web, I'd forget all about the add-on, because it would pop up once in a blue moon. There are no settings whatsoever, either.

Add-on needs improvements on how to pause playback in the browser before starting the 20 second break. I had no option to pause the video when the notification appeared.

Good intentions, needs major work. My timer on my laptop would work better than this.
